Here you can find examples of the interfaces subjects saw during the game, showing the evolution of the screen over time. In the top half (third) of her screen, a subject could see her own past actions and payoffs, while the bottom half (two thirds) of the screen showed her fellow group members’ actions and payoffs. A blue (red) part of the payoff curve indicated that the player used the safe (risky) arm over the corresponding period. The x-axis represented calendar time, while the y-axis gave the player’s cumulated total earnings up to each point in time. There was no prior indication of the point in time the game would end.

All four heatmaps show the total number of fixations. The accumulated number of fixations is calculated for an entire game. Each fixation made has the same value and is indepentent of its duration. A color gradient is used to indicate the areas with more fixations (low=green to high=red).
